Definitions

  • the present invention relates to the field of a battery tester, and more particularly to a battery tester providing high precision detecting results.
  • the battery tester is used to detect the residual capacity of the rechargeable battery to determine the health of the rechargeable battery.
  • the conventional battery tester uses only one method to detect different rechargeable batteries and inaccurate testing results will likely occur.
  • the conventional battery tester uses 1/2 Cold Cranking Amps (hereinafter CCA) testing method to detect the health of the rechargeable battery, the method having steps of: (a) adding a load to the two electrodes of the battery to discharge the battery by loading the amperes of 1/2 CCA for 15 seconds; and (b) determining the health of the battery according to the discharging diagram.
  • CCA 1/2 Cold Cranking Amps
  • the resistance of the load and the duration of adding load to the battery are fixed. Therefore, when the battery tester respectively detects rechargeable batteries with different capacities, figures of the discharging diagrams are not precise.
  • the testing precision of the conventional battery tester is not ideal for all rechargeable batteries.
  • a battery charger with the features of the preamble of claim 1 has become known from US 2006/244423 A1 .
  • Other similar battery testers are described in US 6369577 B1 , US 6259254 B1 , US 5773977 A , US 4707795 A and US 2009/237086 A1 .
  • the present invention provides a battery tester with high precision to mitigate or obviate the aforementioned problems.
  • the main objective of the present invention is to provide a battery tester with high precision.
  • the battery tester has a casing having an input device and two detecting wires, a microprocessor, a loading unit and a battery power status detecting unit.
  • the microprocessor stores a strategic decision process therein to determine a loading time for a battery according to the cold cranking amperes of the battery, the battery voltage and detection requirements including a 1/N CCA and a loading time input from the input device. Therefore, the battery tester detects batteries with different cold cranking amperes and has accurate detecting results.
  • a preferred embodiment of a battery tester in accordance with the present invention has a casing 10, a microprocessor 20, a loading unit 21, a switch 211 and a battery power status detecting unit 22.
  • the casing 10 has an input device 11 and two detecting wires 12. A user uses the input device 11 to select a specific battery capacity.
  • the detecting wires 12 are respectively and electronically connected to two electrodes 31 of the battery 30. In the preferred embodiment, the two detecting wires 12 respectively clip to the two electrodes 31 of the battery 30.
  • the casing 10 further has a display 13, a computer connector 14 and an alarm 15.
  • the computer connector 14 is used to connect to an external electronic device such as a computer or mobile phone.
  • the microprocessor 20 stores a strategic decision process and a detecting process therein.
  • the loading unit 21 is electronically connected to the microprocessor 20 and the two wires 12.
  • the loading unit 21 is electronically connected to the electrodes 31 of the battery 30 through the two wires 12 to detect voltage and current changes of the battery 30 and then responds with the voltage and current values to the microprocessor 20.
  • the switch 211 is electronically connected between one of the detecting wires 12 and the loading unit 21 and is controlled by the microprocessor 20.
  • the battery power status detecting unit 22 is electronically connected between the detecting wires 12 and the microprocessor 20 to detect the battery voltage value and/or current value. Further, the battery power status detecting unit 22 may be built-in the microprocessor 20.
  • the microprocessor 20 executes a strategic decision process having the following steps of:
  • the battery tester uses a fixed loading unit, but the final loading time is determined according to the cold cranking amperes of the battery and the preset detection requirements including the 1/N CCA and the loading time.
  • the battery can continuously discharge for the final loading time and the microprocessor presets a power threshold and obtains enough discharging power status and a high precision detecting curve to analyze the health of the battery according to the detecting waveform.
  • the detecting curve obtained by the microprocessor 20 and the flow chart of the detecting process are shown.
  • the battery 30 is first charged to full capacity and just removed from a charger.
  • the loading unit 21 is then connected to the battery 30.
  • the microprocessor 20 detects a discharging power of the battery 30 through the loading unit 21 and monitors whether a discharging power of the battery 30 achieves a present power value (V e2 ).
  • V e2 present power value
  • the switch 211 are removed from the battery 30 so the loading unit 21 is disconnected from the battery (S20). Therefore, the battery 30 has no floating charging voltage.
  • the loading unit 21 is alternatively connected to the battery 30 to detect multiple voltage values and current values of the battery 30 (S21).
  • the detecting curve is completed by the voltage values and/or current values and the microprocessor determines the health of the battery according to the detecting curve (S22).
